Regarding Claim 1
Amschler discloses:
An injection device comprising:
(medicine delivery device 800; fig 8)
a medicament container;
(cartridge 810; fig 8)
a signal generator configured transmit one or more signals towards the medicament container,
(paragraph 72-77; transmitter (not enumerated/illustrated) of ultrasonic transceiver 850; fig 8)
the one or more signals configured to excite one or more resonances of the medicament container;
Examiner notes claim language of “configured to” implies a functional language and the prior art must at least be capable of performing the recited function exciting one or more resonances in the medicament container. As disclosed by in paragraph 65-66 of Amschler, an emitted ultrasonic wave signal, such as the ultrasonic signal emitted in the embodiment of paragraph 72-77 and fig 8, can interfere with the reflected signal such an acoustic resonance is excited within the cavity of the container. Thus, the ultrasonic signal emitted by Amschler's transceiver 850 is functionally capable of exciting a resonance of cartridge 810.
a signal detector configured to measure [the one or more signals transmitted by] the signal generator while the signal generator transmits the one or more signals; and
(paragraph 72-77; receiver (not enumerated/illustrated) of ultrasonic transceiver 850 receives the ultrasonic signal transmitted by the transmitter of transceiver 850 while the transmitter is emitting the signal; fig 8)
a processor configured to determine one or more properties of the medicament container based on the measured one or more [signals transmitted by the signal generator].
(paragraph 72-77; processing circuitry (not enumerated/illustrated) of the receiver of the ultrasonic transceiver 850 determines round trip delay/time of flight based on the detected and transmitted signals, therein a time varying voltage/current of electronic information representing the waveform emitted from transceiver 850's transmitter, which is leveraged to determine a length of the cavity, therein a property of, of cartridge 810)
Amschler discloses the elements of the present claim, as described above. Yet, its present embodiment is silent regarding the precise type of signal/unit of measurement measured by the signal detector and examined by the processor for determining a property of the medicament container being that of a voltage or current:
However Nishizu teaches a processing system of invention which determines a resonant frequency of an acoustic cavity system wherein:
the system determines one or more properties of the medicament container based on the measured one or more voltages or currents
(paragraph 28-29+98-100+110-111+143; the voltage signal from the signal generator, coil of speaker 2, is analyzed with respect to the frequency spectrum of the emitted signal to determine a resonant frequency of the acoustic system)
Therefore, it would have been obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention to apply Nishizu’s teachings of analyzing the voltage signal from its transmitter to determine when an acoustic system has reached acoustic resonance to the modified device of Amschler, by replacing Amschler’s transmitter with Nishizu’s speaker 2 such that Amschler’s transceiver 850’s processing circuitry can incorporate the processing teaching of Nishizu to measure the voltage signal from Nishizu’s speaker 2, in order to advantageously arrive at an invention which applies a known technique of utilizing voltage measurements of transmitted signals to make determinations about an acoustic cavity’s properties based on those voltage measurements to a similar known device which relies on measuring signals from an ultrasonic transmitter to make a determination of cavity length, see MPEP 2143(i)(d).
Regarding claim 2, Amschler discloses:

Regarding claim 4, the modified device of Amschler in view of Nishizu discloses:
The injection device of claim 1, wherein the one or more properties include at least one of a size of an interior volume of the medicament container or a position of a bung within the medicament container.
Amschler: (paragraph 72-77; processing circuitry (not enumerated/illustrated) of ultrasonic transceiver 850 determines length of the cavity, therein a size of an interior volume and a relative position of piston820/shaft830 inside, of cartridge 810 based on the detected and transmitted signals)
Regarding Claim 5,
Amschler discloses all of the elements of the current invention which the present claim is dependent upon, as described above. However, Amschler’s present embodiment is silent regarding:
The injection device of claim 4, wherein the processor is configured to determine the one or more properties based on – frequency -- of the measured one or more voltages or currents.

Therefore, it would be obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention, to incorporate Amschler’s alternative means of determining a cavity’s length using a resonant frequency based measurement to Amschler’s disclosed invention of fig 8, in order to advantageously arrive at an invention with multiple redundant means for determining a length of a cavity of a drug container and thus improve the reliability of the invention against failure modes limiting the efficacy of a single one of the measurement means, such as failure to receive/measure a reflected acoustic wave.
However, the presently modified device of Amschler remains silent as to the exact processing which determines that the resonant condition has occurred based on the transmitted signal, and thus is silent regarding the processor configuration of the present claim.
Notably, Nishizu teaches a processing system of invention which determines a resonant frequency of an acoustic cavity system wherein:
the processor is configured to determine the one or more properties based on one or more positive or negative frequency-dependent peaks of the measured one or more voltages or currents.

Therefore, it would be obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention, to apply Nishizu’s teachings of analyzing the voltage signal from its transmitter for a peak value to determine when an acoustic system has reached acoustic resonance to the modified device of Amschler, by replacing Amschler’s transmitter with Nishizu’s speaker 2 such that Amschler’s transceiver 850’s processing circuitry can incorporate the processing teaching of Nishizu to measure the voltage signal from Nishizu’s speaker 2 and determine when the emitted signal has moved Amschler’s device 800 into a resonant condition, in order to advantageously arrive at an invention which applies a known technique of identifying resonant conditions based on a transmitted signal to a similar known device which relies on detecting that resonant condition to make a determination of cavity length, see MPEP 2143(i)(d).

Regarding claim 8, the modified device of Amschler in view of Nishizu discloses:

Further consider paragraph 76 of Amschler notes that that the invention is operable with multiple frequency bands, therein the claimed signal detector is measures the voltage of the signal of the claimed signal generator at the frequency which the signal generator transmits the signal at)

Examiner notes claim language of “configured to” implies a functional language and the prior art must at least be capable of performing the recited function exciting one or more resonances in the medicament container. As disclosed by in paragraph 65-66 of Amschler, an emitted ultrasonic wave signal, such as the ultrasonic signal emitted in the embodiment of paragraph 72-77 and fig 8, can interfere with the reflected signal such an acoustic resonance is excited within the cavity of the container. Thus, the ultrasonic signal emitted by Amschler's transceiver 850 is functionally capable of exciting a resonance of cartridge 810.

Regarding Claim 15,
The modified device of Amschler discloses all of the elements of the current invention which the present claim is dependent upon, as described above. Notably, the presently modified device of Amschler remains silent as to the exact processing which determines that the resonant condition has occurred based on the transmitted signal, and thus, the modified device of Amschler is silent regarding:

Notably, Nishizu teaches a processing system of invention which determines a resonant frequency of an acoustic cavity system wherein:

Claims 3 and 9 are rejected under 35 U.S.C. 103 as being unpatentable over Amschler in view of Nishizu, as applied to claims above, in view of US 10869967 B2 henceforth written as Sleicher.
Regarding Claim 3,
The modified device of over Amschler in view of Nishizu discloses all of the elements of the current invention which the present claim is dependent upon, as described above, including the following limitations of the present claim:
The injection device of claim 1, wherein the signal generator, the signal detector -- are disposed in or on a bung of the medicament container.
Amschler: (paragraph 75, "ultrasonic transceiver 850 located in dispensing piston 820 or shaft 830")
However, the modified device of Amschler in view of Nishizu is silent regarding:
wherein the processor [is] disposed in or on a bung of the medicament container.
However, Sleicher teaches a drug delivery device with a sensor system embedded in its bung, wherein in fig 7 it is illustrated and in col 8 line 34 to col 9 line 51 it is detailed that the sensitive electronics (i.e. transducer, sensor, power, processing circuitry, etc.) are embedded within stopper 700 and surrounded by a material which undergoes a phase change proximate to the temperature which the device is sterilized at in order to protect the electronics from excess heat energy present in the sterilization process which could overheat such sensitive electronics.
Therefore, it would be obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention, to apply Sleicher’s teachings of disposing its sensitive electronics within its stopper of a specific material, to the sensitive electronics disclosed by the modified device of Amschler in view of Nishizu, thus disposing the claimed signal generator, claimed signal detector, and claimed processor within Amschler’s bung and forming Amschler’s bung from Sliecher’s phase change material, in order to advantageously arrive at an invention which protects its sensitive electronics from the sterilization process imposed on medical devices, see col 9 line 7-23 of Sleicher.
Regarding Claim 9,
The modified device of over Amschler in view of Nishizu discloses all of the elements of the current invention which the present claim is dependent upon, as described above, including the following limitations of the present claim:
The injection device of claim 1, further comprising a circuit board disposed in or on a bung of the medicament container, the circuit board comprising -- the signal generator, and the signal detector.
Amschler: (paragraph 75, "ultrasonic transceiver 850 located in dispensing piston 820 or shaft 830"; the circuitry which enjoins the electronic elements of the ultrasonic transceiver 850, such as its transmitter and receiver, is considered the claimed circuit board because of the manner by which it connects electronic elements together to communicate signals therebetween)
However, the modified device of Amschler in view of Nishizu is silent regarding:
a circuit board disposed in or on a bung of the medicament container, the circuit board comprising a processor
However, Sleicher teaches a drug delivery device with a sensor system embedded in its bung, wherein in fig 7 it is illustrated and in col 8 line 34 to col 9 line 51 it is detailed that the sensitive electronics (i.e. transducer, sensor, power, processing circuitry, etc.) are embedded within stopper 700 and surrounded by a material which undergoes a phase change proximate to the temperature which the device is sterilized at in order to protect the electronics from excess heat energy present in the sterilization process which could overheat such sensitive electronics.
Therefore, it would be obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention, to apply Sleicher’s teachings of disposing its sensitive electronics within its stopper of a specific material, to the sensitive electronics disclosed by the modified device of Amschler in view of Nishizu, thus disposing the Amschler’s claimed circuit board and thus also its claimed signal generator, claimed signal detector, and claimed processor within Amschler’s bung and forming Amschler’s bung from Sliecher’s phase change material, in order to advantageously arrive at an invention which protects its sensitive electronics from the sterilization process imposed on medical devices, see col 9 line 7-23 of Sleicher.
Claim 7 is rejected under 35 U.S.C. 103 as being unpatentable over Amschler in view of Nishizu, as applied to claim 6 above, in view of US 5780743 A, henceforth written as Morgan.
Regarding Claim 7,
The modified device of over Amschler in view of Nishizu discloses all of the elements of the current invention which the present claim is dependent upon, as described above, including the following limitations of the present claim:
The injection device of claim 6, wherein a -- frequency of the one or more frequencies of the one or more positive or negative frequency-dependent peaks is indicative of a [harmonic and ] fundamental resonance frequency of the medicament container
Examiner notes that harmonic frequencies of a system are themselves indicative of the fundamental resonance frequency of that system as they are inherently a multiple of that fundamental frequency. Similarly, any harmonic resonant frequency is a harmonic multiple of the fundamental resonance frequency. Therein, the frequency measured by the processing teachings of Nishizu applied to the modified device of Amschler is indicative of both the harmonic resonance frequency and a fundamental frequency.
However, the modified device of Amschler in view of Nishizu is silent regarding the processor measuring multiple harmonic frequencies to identify multiple positive or negative frequency-dependent peaks indicative of harmonic resonance and fundamental resonance frequencies of the one or more resonances of the medicament container.
However, Morgan teaches an invention for determining a resonance condition in a fluid filled cylinder wherein in col 3 line 60 to col 4 line 48 and figure 3 it is taught that when the invention identifies multiple higher order harmonic frequencies, the first order harmonic frequency aka the fundamental resonant frequency may be identified and locked on to accurately calculate a resonant frequency by limiting the noise which is amplified in higher order resonant frequencies.
Therefore, it would be obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention, to apply Morgan’s teachings of identifying multiple higher order harmonic frequencies to hone in on a base fundamental frequency for determining a resonant frequency of the system to the processing system disclosure of the modified device of Amschler in view of Nishizu, in order to advantageously arrive at an invention which “permits calculations that yield highly accurate resonance frequency values”, see col 4 line 31-32 of Morgan.
Claim 10 is rejected under 35 U.S.C. 103 as being unpatentable over Amschler in view of Nishizu, as applied to claims above, in view of US 4285053 A, henceforth written as Kren.
Regarding Claim 10,
The modified device of Amschler in view of Nishizu discloses all of the elements of the current invention which the present claim is dependent upon, as described above. However, Amschler in view of Nishizu is silent regarding:
The injection device of claim 1, wherein the signal detector comprises an impedance measurement circuit comprising a diode, a capacitor, and an analog-to-digital converter electrically connected to a node between the diode and the capacitor.
Examiner notes that the present embodiment of Amschler relies upon detecting a difference in a phase shift of an ultrasonic wave to determine time of flight of a transmitted acoustic wave to determine a length of its acoustic cavity, see paragraph 72-77, however, it does not recite the exact processing technique/structure which determines this phase shift to perform the consequent cavity length determination.
However, Kren teaches a distance gauge which relies upon phase shifts in transmitted/received acoustic waves to determine a distance which great accuracy
wherein the signal detector comprises an impedance measurement circuit
(circuit (not enumerated) of fig 3, excluding oscillator 25 and wire 15, detects signals from the microphone 33 via the circuit’s wires 35 and from oscillator 25 via the circuit’s wires 36, and thus may be equated to a signal detector which has circuitry to measure/record the effects of the acoustic impedance of the system, therein an impedance measurement circuit; fig 1-3)
comprising a diode,
(diode 47; fig 3)
a capacitor, and
(capacitor 57; fig 3)
an analog-to-digital converter electrically connected to a node between the diode and the capacitor
(analog-to-digital converter 63; fig 3; see examiner’s annotation of Kren’s fig 3 denoting the node between the diode 47 and capacitor 57 which converter 63 is electrically connected to)

Therefore, it would be obvious to a person of ordinary skill in the art before the effective filing date of the claimed invention, to import the signal processing means and structure taught by Kren into the signal detector and processing circuitry disclosed by Amschler, as Amschler is silent regarding the exact signal processing means it relies upon to measure its acoustic signal’s phase shift in determining its cavity length/distance and applying the known technique of Kren would advantageously provide means for measuring this phase shift with micron level accuracy, see col 1 line 51 to col 2 line 2.
